绘制多个子图动画 [英] Plotting multiple subplot animations

问题描述

我目前正在尝试在 2x2 matplotlib 矩阵中绘制四个同步动画.我的代码如下:

I am currently trying to plot four simultaneous animations in a 2x2 matplotlib matrix. My code is as follows:

x1 = np.random.normal(0, 1, 1000)
x2 = np.random.gamma(0, 1.5, 1000)
x3 = np.random.exponential(2, 1000)
x4 = np.random.uniform(0,20, 1000)

import matplotlib.animation as animation
n = 1000
def update(curr):
# check if animation is at the last frame, and if so, stop the animation a
 if curr == n: 
    a.event_source.stop()
 plt.cla()
 fig , ax = plt.subplots(2,2,figsize=(5,3),sharex=False,sharey=False)
 ax[0,1].hist(x1[:curr],bins=50,alpha=0.5,normed=True)
 ax[0,0].hist(x2[:curr],bins=50,alpha=0.5,normed=True)
 ax[1,0].hist(x3[:curr],bins=50,alpha=0.5,normed=True)
 ax[1,1].hist(x4[:curr],bins=50,alpha=0.5,normed=True)

fig , ax=plt.subplots(2,2,figsize=(5,3))
a = animation.FuncAnimation(fig, update, interval=100)

子图由艺术家绘制，但动画从未填充直方图.没有错误解决，Jupyter 将该行标记为完整.知道发生了什么吗?

The subplots are drawn by the Artist, but the animation never fills in the histograms. No error resolves and Jupyter marks the line as complete. Any idea what's happening?

推荐答案

如果你想在你的 jupyter notebook 中看到动画，你需要在你的脚本之前添加 %matplotlib notebook.

You need to add %matplotlib notebook before your script if you want to see the animation inside your jupyter notebook.
